no fluid was in my front transfer case

New to me 1993 KS4 and I am changing the transmission fluid. Bask seemed a tad low but drained well, kinda dirty. I take of filler plug on front and nothing followed by removing the drain plug also nothing. How f'd am I? 4WD seemed to have been operational so I'm not sure.

 

How many km total? How many km since it came from Japan?

 

38807 km. I’ve put maybe 5 of those on myself

 

I should add that it is fresh off the boat from Japan. Putting new fluids in today so hopefully all is well.
